Introduction:
The GO-400N is an industrial online ORP (Redox) composite sensor with a special glass body. It is composed of a platinum indicator electrode and a silver-silver chloride reference electrode, designed for the detection of oxidation-reduction potential (ORP) in demanding applications such as circuit board wastewater treatment and chromium-containing wastewater treatment.
It features a special glass sensitive membrane, circular anti-pollution PTFE diaphragm and maintenance-free gel electrolyte salt bridge. The body is made of special glass with a PTFE protection cover (Pg13.5 inner thread / 3/4" NPT outer thread), providing good chemical resistance for harsh media. It supports plug-in installation and is available with Pin, Y or BNC cable connector.
Key Features:
-Glass body design — special glass housing with PTFE protection cover for good chemical resistance
-Combined electrode— platinum indicator electrode + silver-silver chloride reference electrode
-Special glass sensitive membrane — suited for circuit board & chromium-containing wastewater
-Maintenance-free— gel electrolyte salt bridge, no refilling required
- Anti-poisoning & anti-pollution— gel salt bridge and circular PTFE diaphragm prevent poisoning and clogging
-Flexible connector— Pin, Y or BNC cable connector
-Plug-in installation— with PTFE protection cover (Pg13.5 inner / 3/4" NPT outer thread)
